Geeks: We've Got Your Number

Regular numbers? Those are for amateurs. Bring your inner genius out for all to envy with a smart and stylish watch that features the equivalent notation of each number.

For nascent mathematicians and victims of the occasional memory lapse, a cheat sheet is included with each watch.:
1: i is equal to the square root of -1, so i^2= -1. The absolute value of -1 is 1.
2: This represents 2 in binary code.
3: The cube root of 27
4: 11 base 3, which represents 4 in the ternary system
5: Log(20x)=2 is equivalent to 20x=10^2 or 20x=100, where x=5.
6: Euler's product formula: phi(p^k)=(p^k)(1-(1/p)), where (p^k)=9
7: This is a binomial coefficient, so with the formula n/k = (n!)/((k!)(n-k)!), n/k=7.
8: This is a natural logarithm where ln(e^x)=x, so ln(e^8)=8.
9: This summation is equal to 3(1)+3(2)=3+6=9.
10: Since clocks "wrap around" every 12 hours, the hour number starts over after it reaches 12. This is arithmetic modulo 12. 10mod12 is 10:00, and 16mod12 would be 4:00, for example.
11: B'L is Legendre's constant, which is equal to 1, so this equation becomes the square root of 121, which is 11.
12: Hexadecimal representation of 12

    The product looks great, great quality. Too bad it's too big for a woman's small wrist. The side rubs against the hand.

            I bought this watch for my husband, he loved it ! However with normal movement, the watch scratches his wrist, other than that this watch makes for an interesting gift.

                My brother mentioned at Thanksgiving he had seen some neat watches, all well out of my price range. Then Uncommon Goods arrives with a watch made for
                the guy who does complicated math in his head.

                  My husband has shown this to everyone! He is not into stuff and buying him gifts is usually a huge challenge. He loved this watch and told me I knocked it out of the park! To be honest, I don't know most of the math terms-but he does!

                      Perfect gift for the ultimate nerd. Boyfriend and his friends all love it, and it is definitely a conversation starter. The face of the watch is a lot bigger than I expected, which was great. Subtle enough to pass off as a "normal" everyday watch. Bought it in black and it was perfect.

                      I bought this as a gift for a birthday and graduation in college for a friend I liked. She never received it and because of that I didn't open it. I still think it's great and rather my fault for not being good enough.

                        From the picture, I was worried that the strap would be a bit stiff or hard. But turns out it was very soft! The watch's crystal has a nice shine as well. Overall, the product is great, and I'd want to buy a second one for myself!
